Your suggestion makes sense *for new US english patterns*. The
existing patterns from Knuth must not be changed for legal reasons (or
some sort of that).
For groff you can do the following.
1. Set up all latin-1 characters for hyphenation (using the `.hcode'
request, cf. file `de.tmac').
2. Add all words with non-ASCII characters to an additional
hyphenation exception list and load it (cf. file `hyphenex.us').
On a global level, unfortunately, nothing will happen until a new
maintainer for US english hyphenation patterns appears.
